[PaulNZ]

Cobbled this together from some stuff I found online.

Name: PowerShell: Get DFS-R Backlog
Hint: Params: <Group Name> <Folder Name> <Sending Member> <Receiving Member> <Backlog Threshold>

Start cmd: powershell.exe %script% %params%
Script:

Code: Select all

$statusAlive       = "ScriptRes:Host is alive:"
$statusDead        = "ScriptRes:No answer:"
$statusUnknown     = "ScriptRes:Unknown:"
$statusNotResolved = "ScriptRes:Unknown host:"
$statusOk          = "ScriptRes:Ok:"
$statusBad         = "ScriptRes:Bad:"
$statusBadContents = "ScriptRes:Bad contents:"

if (!$args[4]) {
  echo  $statusUnknown"Insufficient parameters provided"
  exit
}

$ReplicationGroupName = $args[0]
$ReplicatedFolderName = $args[1]
$Smem = $args[2]
$Rmem = $args[3]
$BacklogThreshold = $args[4]

$WMIQuery = "SELECT * FROM DfsrReplicatedFolderInfo WHERE ReplicationGroupName = '" + $ReplicationGroupName + "' AND ReplicatedFolderName = '" + $ReplicatedFolderName + "'"
$OutboundPartnerWMI = Get-WmiObject -computername $Smem -Namespace "root\MicrosoftDFS" -Query $WMIQuery
$InboundPartnerWMI = Get-WmiObject -computername $Rmem -Namespace "root\MicrosoftDFS" -Query $WMIQuery
$VersionVector = $InboundPartnerWMI.GetVersionVector().VersionVector
$BacklogCount = $OutboundPartnerWMI.GetOutboundBacklogFileCount($VersionVector).BacklogFileCount

if ($BacklogCount -le $BacklogThreshold) 
{
   echo $statusOk$BacklogCount" Files"
} 
else 
{
   echo $statusBad$BacklogCount" Files"
}
